Here are some health tips from the China CDC for drinking water during the summer heat.
Tips for drinking water in summer
Don't wait until you are extremely thirsty to drink. If you're thirsty, you're already dehydrated, which means your body has lost its water balance.
Don't drink too much water when you are extremely thirsty. Drinking water in this way will make it difficult for the stomach to adapt and cause harm to the body.
Don't drink too much water before meals, it will dilute the digestive juice, which is not conducive to the digestion and absorption of food. This can bring adverse effects on digestive function in the long run.
It is recommended to drink a cup of boiled water after getting up in the morning to supplement the water loss overnight. This habit can also reduce blood viscosity, promote blood circulation and maintain the normal level of body fluids.
People who should pay more attention to hydration
The elderly are less sensitive to thirst, so they are often in a state of water shortage and prone to constipation or high blood viscosity, which can easily affect their cardiovascular system.
Children exercise a lot and need to replenish water frequently. Moreover, children are fond of playing and easily forget to drink water. They will drink a lot of water only when they are particularly thirsty, which will affect the normal absorption of water by the human body and be harmful to their health.
Babies have a high metabolism. The amount of water that needs to be replenished for them is higher than that for adults. Although infants mainly consume liquid food, it is recommended they drink water between breast feeding.
